First-team coach Kevin Lynch admitted after Saturday's friendly against Huddersfield that manager Paul Cook faces some tough decisions over the future of the various trialists who are at the club.
Former Hull City man Jamie Devitt scored the second goal in a 2-1 win with a well-taken free-kick to press his claims for a contract. Lynch said: "Jamie has got that in his locker. We're still looking at him and he's done his chances no harm."
Other trialists in action were Ritchie Humphreys, Matty Brown, John Shaw, Conor Clifford and Hendrick Cakin, who have all been involved in pre-season training. When asked whether any of them would be offered deals, Lynch commented: "I think there are some tough decisions that the gaffer has got to make."
Lynch was delighted with the performance against Championship opposition on a very hot and sunny day at the Proact. "I thought it was an excellent work-out for all the lads," he said. "The work-rate, the movement, the passing and everything we've been working on the training ground came out. It was a pleasing performance.
"One of the messages that we're giving to the players is that they've got to be fit with the energy and the tempo that we're looking to play. It's important that the work they put in on the training ground is put into practice on the field."
The former Marine boss explained the thinking behind the decision to experiment with different formations and try players in different positions. He said: "The gaffer is always looking to come up with a 'plan B' at times so that's what we're trying to work on now."
Lynch acknowledged that one of the stand-out performers was Gary Roberts, who scored the opening goal on his first appearance in a Spireites shirt at the Proact. "Gary's going to excite people at the club because he's got fantastic ability," added Lynch. "With his goal and some of his passes, I thought he was excellent and there's a lot more of that to come."
